Prep the Noodles: Cook the wide rice noodles according to the package instructions. Once cooked, drain and set aside.
Prep the Tofu: If using extra firm tofu, drain and cut into bite-sized cubes. If using silken tofu as an egg substitute, simply drain it. No need to press the tofu for this recipe, but make sure to drain off as much moisture as possible.
Prepare the Marinade: In a bowl, combine soy sauce with a hint of sriracha. Adjust to taste. Mix well and set aside.
Stir-fry Tofu: In a large wok or frying pan, heat a splash of oil over medium heat. Once hot, add the tofu cubes or silken tofu. Stir fry until they are slightly golden, ensuring they're well-cooked but not overly crispy.
Add Vegetables: Increase heat to medium-high. Add the bok choy and mung bean sprouts to the pan with tofu. Stir fry until the vegetables are tender yet still crisp.
Add the Noodles: Introduce the cooked wide rice noodles to the wok or pan. Stir everything well.
Pour the Marinade: Drizzle the soy-sriracha marinade over the noodle mixture. Stir-fry for another 1-2 minutes, ensuring everything is well coated and heated through.
Serve: Dish out your Vegan Pad See Ew onto plates. Top with crumbled peanuts. Serve with a grapefruit wedge on the side.
